To all whom it may concern:

Be it known that'I, CHARLES OISHEI, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Seal-Locks, of which the following is a specification.

This invention relates to a seal lock which is more particularly designed for use on the doors of freight cars for the purpose of preventing opening of the doors and tam- "pering with the contents thereof without detection by the parties having supervision of the cars, although if desired this seal lock may be also used for other purposes.

It is the object of this invention to'produce a lock of this character which is simple in construction and capable of easy operation and which is so designed that all of the parts thereof are permanently connected with the car or other body to which the same is applied.

In the accompanying drawings: Figure 1 is a fragmentary side elevation of a box freight car equipped with my improved seal lock. Fig. 2 is a front elevation, on an en.- larged scale, of the seal lock embodying my invent on and showing the parts thereof in a closed and sealed condition. Fig. 3 is a similar view of the same showing the parts thereof in an opened or unsealed position. Fig. 4 is a side elevation of the seal lock in its closed osition. Fig. 5 is a vertical longitudinal section of the seal lock taken in line 5 5, Fig. 2, showing the same in its closed or locked position. Fig. 6 is a similar view showing the parts thereof in an open position. Fig. 7 is a vertical transverse section, taken in line 77, Fig. 4. Figs. 8 and 9 are horizontal sections in the corres ondingly numbered lines in Fig. 2. Fig. 10 is a detached perspective view of one of the seals for holding the lock in its closed osition.

Similar characters of reference indicate corresponding parts throughout the several views. 1

Although my improved seal lock is capable of beini used in various ways for protecting inclosures. or rooms containing merchandise from which unauthorized persons are to be excluded I have shown the same hasp 5 is cannot be opened and its passageway uncovered without detection on the part of the persons having charge of the same.

In 1ts general organization my improved seal lock comprises an upright base plate 3 Wh1Cl1iS secured to the outerside of the .body of the car in any suitable manner so that it cannot be removed. on its lower part this base plate is provided with a forwardly projecting perforated lug i. A pivotally connected at one end with the outerside ofthe door and provided at its free. end with. aislot or opening 6 which is adapted to engage with the locking lug 1 in the closed position of the door.

A vertically movable locking bolt 7 is adapted to pass through the'opening' of the locksame after the same has been partly lifted by engaging its lower end.

11, 12 represent two locking arms one of which, preferably the left 11, is adapt d to be arranged fixedly in an upright position above the bracket 8 and on one side of the vertical path'of movement of the locking bolt, while the other arm'12 is adapted'to be moved into and out of a vert cal position above said bracket so as to either proiect across thepa h of the locking bolt or clear said path. For th s purpose the lower end of the fix d arm 11 isconnected at its lower end with the front part of the lower b a cket 8 and its upper end is connected with an upper bracket 13 proiecting forwardly from the upper part. of. the base plate, and the movable arm 12 is pivotally connected .at its/upper end by means of a rivet 14. as

the fixed arm and with the upper bracket, so that the lower end of the mo able arm may be swung in a vertical plane either across the'path of the lockingbolt or out of. said path. .Vhen the locking bolt is in its de pressed-position and the movable locking arm is swungacross the path of the locking shown or otherwise, with the upper end of bolt the lower end of this arm is arranged above the upper end of a locking bolt, as shown in Figs. 2, 5 and 7, thereby preventing the locking bolt from being raised and confining the hasp 5 on the locking lug Upon swinging the movable locking arm outwardly so as to clear the path of the locking bolt the latter is free to be lifted for disengaging its lower end from the looking lug and releasing the hasp so as to permit of sliding the door into an open position. With these locking arms are associated seal controlled means which operate, when a seal is inserted between these arms, to, cause the same to become automatically locked together upon swinging the movable locking arm into its operative position and to hold these arms into this relative position so long as the seal between the same remains intact. In its preferred means this automatic fastening device comprises a bodily fixed catch, latch or hook 15 pivotally supportedwithin a pocket 16 on the fixed locking arm by means of a pin 17 formed on thisarm and yieldingly held in its raised or inoperative position by means of a spring 18 mounted on a'pin 19 arranged on this locking arm within its pocket and having a lower arm engaging with the bottom of its pocket and an upper arm engaging with the underside of the catch 15.

WVithina pocket 20 formed in the lower part of the movable locking arm and pivotally mounted on this arm by means-of a pin 21 arranged in the pocket thereof is another locking catch or latch22 which is yieldingly held in its elevated or operative position by means of a spring 23 mounted on a pin 24 within the pocket of the movable locking arm and having an upper arm engaging with the underside of the respective catch and a lower arm engaging with the bottom of the respective pocket. The nose of the bodily fixed catch or latch on the 'fiXSd arm is arranged on the inner end of this latch and projects downwardly while the nose of the bodily movable catch orlat'ch on the movable lockingarm is also arranged on the inner end of the last mentioned catch and projects upwardly. In the absence of a seal between the opposing edges of the locking arms the bodily fixed latch or catch is held in its inoperative position indicated dotted lines in'Fig. 5 and by full lines in Fig. 6 by the action of itsspring in which position of the same the nose thereof is arranged above the path of'the nose of the bodily movable latch or catch so thateach nose of these two catches cannot become interlocked with each other upon swinging the movable locking arm into or out of its operative position, thereby leaving the movable locking arm free to be swung outwardly and the locking bolt free to be raised so as to permit of either applying the hasp over'the locking lug 4 or removing the same therefrom. When, however, the bodily fixed catch is depressed into its operative position in opposition to the resilience of its spring,

its nose is arranged in the path of the nose 1 on the bodily movable catch, so that upon lowering the locking bolt into its operative position through the locking lug and then swinging the movable locking arm inwardly over the upper end of the locking bolt, the

means of a seal which is preferably con.-

structed of frangible material such as glass, porcelain or plaster-of-Paris and has a circular body 25 which is adapted to be seated with opposite halves of its peripheral or marginal portion in two semicircular grooves or seats 26, 27 formed inthe opposing edges of the locking arms between the pivot 14 and the pockets thereof. Upon placing such a seal within these semi-circular seats and swinging the movable lock ing arm inwardly toward the fixed locking arm this seal will be confined between these arms and the lower edge portion of the seal will operate as acam or wedge which deflects the bodily fixed catch downwardly from its inoperative position to its operative position and the bodily movable catch will engage its nose with that of the bodily fixed catch, thereby connecting the locking arms and preventing the locking bolt from being raised, as shown in Fig. 5. lVhen it is desired to openthe door of the car the seal is broken by a hammer or otherwise and as the pieces of the sealare discharged from between the opposing locking arms, the bodily fixed catch is released permitting its springto raise the same from its operative position in which its bill engages with that of the bodily movable-catch into an in operative position in-which its nose is disengaged from'that of-the bodily movable catch, thereby permitting the movable looking arm to be swung laterally out of the path of the bolt and enabling'the latter to be raised, so that the hasp can be removed from the locking lug 4 and the door moved into its open position.

The upper and lower brackets 13,8, support the upper and lower ends of the looking arms'at a distance from the base plate so as to form an interveningspace 28 between. the base plate and the'arms. This space furnishes the necessary --room into which the fragments of-the'brokensealare driven. when delivering a'blow against the without interfering with the subsequent resetting of the seal lock for again sealing the car. In order to permit of more quickly and conveniently removing any small par.-

ticles of the seal which may remain .in the 1 grooves or seats of the locking arms each of these arms is provided. in the walls or flanges of these seats about midway between the upper and lower edges thereof with notches or passageways 29 through which any seal fragments can be readily ejected by means of the fingers. The front side of the seal may be provided with an inscription of any suitable character indicating the name of the railroad, manufacturer or shipper under whose direction the car was sealed, the number of the car or any other identifying mark. In order to always retain this seal between the locking arms in a position in which the seal may be conveniently read, the front side of the seal is provided with a transverse rib or projection 30 which preferably extends diametrically across the same and is adapted, in the closed position of the locking arms to engage with the front notches in the front walls of these arms, thereby locking the seal againstrotation and insuring retention of the same in a position in which the inscription or data on the front side of the same can be easily read.

In order to reliably support the lower ends of the locking arms against inward or rearward displacement when the seal is broken by a blow from the front side, a supporting or retaining flange or rib 31 is provided which projects forwardly from the base plate above the lower bracket and engages with the rear side of the locking arms preferably adjacent to the lower end of the seal receiving seats thereof, as shown in Figs. 4, 6 and 7.

It will be obvious from the foregoingda scription that so long as the seal remains intact between the locking arms the car' arranged in the path of the locking bolt when in their operative positions, and seal controlled means for holding one of said locking arms in its operative position.
